Blue Danube Systems completes FDD LTE Massive MIMO commercial trials with Shentel and AT&T
Blue Danube Systems, a provider of mobile wireless access solutions, has announced that it has completed first commercial trials of its Massive multiple-input multiple-output (MIMO) system in licensed FDD (Frequency Division Duplex) LTE spectrum.
The trials used Blue Danube’s BeamCraft 500 active antenna product for advanced 3D beamforming, which can deliver 160W of transmit power for a Massive MIMO system. Based on its underlying High Definition Active Antenna System (HDAAS) technology, the 96 element BeamCraft 500 can intelligently and seamlessly focus signal energy where it is needed, allowing wireless carriers to better serve high demand areas and minimise interference zones.
These trials were conducted with Shenandoah Telecommunications Company (Shentel) and AT&T, an investor in Blue Danube Systems, and supported more than 10TB of data during a three-month period. Through a simple retrofit of the existing antenna with a BeamCraft 500 unit at the trial sites, an 2-5-fold improvement in throughput was demonstrated for users in high traffic demand areas for the same transmit power as the legacy installation. Additionally, users received up to a 20-fold improvement in instantaneous video throughput and experienced smooth 1080p HD videos in locations where existing systems were stalling and previously only capable of 144p. A second phase of trials is now ongoing to test additional operational modes and traffic scenarios.
